Highest temperature in Paris on July 27?

Platform comparison

Market context

On 27 July 2026, the highest temperature recorded at Paris-Le Bourget Airport will determine which range this market settles into. Historical July data for the station shows typical highs between 24–28°C, with occasional peaks above 30°C during heat waves. The current 0% probability assigned to the YES outcome suggests traders are pricing in either extreme confidence in a specific temperature band or minimal liquidity depth in this particular contract. Comparable European airport weather markets have shown that summer temperature ranges cluster predictably when settlement windows close within 24 hours of the actual event, reducing forecast uncertainty significantly compared to longer-dated weather contracts.

The Paris region experiences variable summer conditions influenced by Atlantic weather systems and occasional continental heat surges from southern Europe. Mid-to-late July typically sits within the warmer portion of the French summer, though 2026 forecasts remain unavailable at this distance. Traders monitoring this market should track European weather model updates as July approaches, particularly from Météo-France and the European Centre for Medium-Range Weather Forecasts, which publish 10-day outlooks roughly two weeks prior to settlement. The settlement window closes at 12:00 UTC on 27 July, meaning final trades must clear before morning European time, creating a compressed trading window for late-arriving information.

Depositing via Klarna or SEPA transfers allows traders to build positions ahead of the forecast-refinement period. Withdrawal rails through the same payment methods mean settlement proceeds can be accessed without intermediary friction once the Wunderground historical record confirms the day's peak temperature.
